What is HDCP?

High-bandwidth Digital Content Protection (HDCP) is a copy-protection technology used to protect digital content as it travels across connections like HDMI and DisplayPort. It prevents unauthorized copying of digital audio and video content. It works by encrypting the video signal transmitted between a source (e.g., a Blu-ray player) and a display (e.g., a TV). If a device in the chain doesn't support HDCP, the content might be displayed at a lower resolution or not at all.
